Vacuoles Can function as a Storage Organelle Vacuoles can store many types of molecules, in particular essential substances that are potentially harmful if present in bulk in the cytoplasm. Vacuole, in biology, a space within a cell that is empty of cytoplasm, lined with a membrane, and filled with fluid. The waste products the vacuole contains are slowly broken down small enough so it cannot hurt the cell. Vacuoles are present in both plant and animal cells. The cell sap stores food reserves, pigments, defensive toxins, and waste products to be expelled or broken down. mitochondria 5.
